The larvæ, which have no humps, feed on trees, and change to the chrysalis state in light silken cocoons.
The Common Wave (Cabera exanthemata)
The first of our two examples of this small family is the Common Wave, the wings of which are pale grey, almost white, dusted all over with small dark dots. The fore wings are crossed by three parallel and equidistant darker transverse lines, and the hind pair by two. The male may be distinguished by its ciliated antennæ.
The caterpillar is yellow or greenish yellow, with hinder segments slightly swollen. It feeds during the latter part of the summer on sallows (Salix caprea and S. cinerea) and alder (Alnus glutinosa), and changes to a chrysalis in a light cocoon among fallen leaves. In this state it spends the winter, the perfect insect emerging in May or June.
This species is very abundant in most parts.
The Clouded Silver (Bapta temerata)
